DYEING AND BLEACHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 372,472, dated November 1, 1887.

Application filed April 6, 1887. Serial No. 233,938. (No model.) Patented in Germany July 1, 1882, No. 20,691, and January 16, 1883, No. 23,357; in Belgium July 12, 15382,N0. 58,449, and in England July 12, 1882, No.3,308, and March 7, 1883, No. 1,223.

To aZZ whom, it may concern:

Be it known that I, GUSTAV JAGENBURG, a subject of the King of Sweden, residing at the city of Rydboholm, in the Kingdom of Sweden, have invented certain new and use ful Improvements in Apparatus for Dyeing and Bleaching Textile Fibers, (for which Letters Patent have heretofore been granted to me in the following countries, viz: by the Government of Germany, No. 20,691, dated July 1, 1882, and No. 23,357, dated January 16, 1883; Belgium, No. 58,449, dated July 12, 1882; England, No. 3,308, dated July 12,1882, and No. 1, 223, dated March 7, 1888,) of which the following is a specification.

Heretofore it has been customary in mordanting and dyeing loose cotton to boil or cook the same for a number of hours in a mordant or coloring solution. This has the disadvantage that the elasticity of the fibers is ruined and the fiber cannot be spun on an ordinary spinningmachine.

The object of my invention is to provide a new and improved process for dyeing loose cotton without requiring the boiling process, all as will be fully described and set forth hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of my improved apparatus for dyeing and bleaching textile fabrics. Fig. 2 is a side view of the re ceptacle for the cotton, the same being tilted, parts of the frame being in section. Fig. 3 is a horizontal sectional view of said vessel.

Similar letters of reference indicate corresponding parts.

In carrying out my process the loose cotton is impregnated in cacao at a low or medium temperature with proper solutions. For example, if I wish to dye with aniline colors the loose cotton is impregnated in a vacuum apparatus with a solution of tannin, catechu, or other substances containing tannin, and when the cotton is thoroughly impregnated it is re moved from the apparatus, and the surplus of the tanning-liquid is removed by means of a centrifugal machine. The loose cotton is then placed into another vacuum apparatus and is treated with a solution of metal salts-for instance, oxalate of antimony, (lento-sulphate of copper, or deuto-acetate of copper-for the purpose of fixing the tannin on the fiber. The cotton is then removed from the apparatus and placed in a centrifugal machine for the purpose of removing the surplus of the solution of metal salts. The cotton which has thus been mordanted is washed, and can then be dyed by means of aniline colors. For instance, for dyeing black, brown, or gray I proceed as follows: At a low or medium temperature the loose cotton is impregnated with a solution of logwood for black, catechu for brown, and a mixture of catechu and logwood solution for gray, all in a vacuum apparatus. The cotton is then centrifuged and then placed into a second apparatus for the purpose of fixing and developing the color by means of a mordant.

The vacuum apparatus which I use for treating the cotton consists in a vessel, 0, mounted to turn on the two pivots A and B, of which the latter is made tubular. The strength of the vessel G must be such that it can resist an exterior pressure of about fifteen to twenty pounds. The vessel 0 is closed by means of a cover, D, suspended by means of a chain or rope passed over pulleys on a derrick or crane, U, above the same. Said cover is also provided with flanges for receiving a rubber packing-ring, F, for the purpose of forming an absolutely air-tight joint. A dome, E, is provided on the cover, and in the upper end of the dome a valve, G, is provided, which is connected with a float, H, in the dome, which can close one end of a pipe, J, leading from the dome, said dome being in communication with the interior of the vessel 0. The pivot A is provided with a work, S, which can engage with the worm-wheel T, whereby by turning said worm-wheel the vessel can be tilted. The pipe L connects the tubular pivot B with a vessel, K, below the vessel 0, the pipe L being provided with a valve, M. The lower end of said pipe extends to near the bottom of the vessel K. The pipe N connects the tubular pivot B with the bottom of the vessel 0. A pipe, Q, extends from the bottom of the vessel 0 to the vessel K and has a cock, It. A false bottom, 0, is arranged in the vessel 0, and from said false bottom a series of perforated -dant or coloring solution from the vessel or tank K through the pipes L and N into the vessel 0. The liquid rises and lifts the float H, whereby the valve G in the pipe J is closed. Then airis admitted through the pipe J into the vessel 0, the cover D is removed, and the liquid drawn ofi" through the pipe Q into the vessel K. Then the vessel 0 is tilted, as shown in Fig. 2, so as to discharge the cotton.

The same process and apparatus may be used for bleaching cotton, whereby the necessity for boiling or putting the cotton in a bleaching process is prevented.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The combination of the vessel 0, mounted on pivots, of which one is hollow, a pipe having' a cock connected with the hollow pivot, and a pipe connecting the above pivot with the bottom of the vessel, substantially as shown and described.

2. The combination, with a vessel having pivots, of which one is hollow, of a pipe conneeting the hollow pivot with the bottom of the vessel, a false bottom a short distance above the real bottom of the vessel, and up-- right perforated pipes projecting upward from the false bottom of the vessel, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GUSTAV JAGENBURG.
